Hmmm, given all the Stormtroopers, Bucket Helmets, and Wagnerian Film Score (not to mention numerous interviews with Lucas

), I thought it was an obvious allegory for Nazi's/French Vichy vs the Underground Resistance. I haven't read the book you mentioned Eldorion, but I know Lucas himself talks about being inspired by the events of WW2 in nearly every interview he's given. This is the first I've ever heard that he was inspired by the events of Vietnam, though it's certainly plausible that he might have also been inspired by North Vietnamese villagers fighting against the Imperial Armies of the US
